# A mass of 13.4*g was confined to a volume of 186*mL. What is the density of this material?

$\rho \cong 0.07 \cdot g \cdot m {L}^{-} 1$
By definition, ${\rho}_{\text{density"="Mass"/"Volume}}$. We were given a mass and a volume, and thus we just have to work out the quotient:
rho="Mass"/"Volume"=(13.4*g)/(186*mL)=??*g*mL^-1
